Abstract

L'invention se rapporte à des techniques de création de disques de stockage de données optiques. Dans un mode de réalisation, l'invention concerne un procédé consistant à disperser des perles simultanément sur deux faces par passage d'un rouleau. Par exemple, un procédé peut consister à positionner une première perle de photopolymère à disperser entre une matrice inférieure et un substrat, et à positionner une seconde perle de photopolymère à disperser entre une matrice supérieure et un substrat. Le procédé peut également consister à faire passer un rouleau sur la matrice supérieure afin de disperser les perles de photopolymère, à réticuler le photopolymère, et à retirer le substrat des matrices. Ce procédé peut être répété sur le même support pour créer un support de stockage de données bicouche double face, ou un support de stockage de données multicouche double face.
